RTI International, . U., & Southwest Research Institute, . U. (2007). PUREM North America, LLC, PMF GreenTec 1004205.00.0. (The Environmental Technology Verification Program - Control of Emissions from Mobile Diesel Engines in Highway Use by Diesel Oxidation Catalysts and Diesel Particulate Filters; No. EPA Cooperative Agreement No. CR831911-01-1). Research Triangle Park, North Carolina: U.S. Environmental Protection Agency, Office of Research and Development.


This report reviews the performance of the PMF GreenTec 1004205.00.0 diesel particulate filter (DPF) system comprising a precious metal diesel oxidation catalyst (DOC) and a DPF submitted for testing by PUREM North America, LLC (PUREM). Environmental technology verification (ETV) testing of this technology was conducted during a series of tests in September-October 2006 by Southwest Research Institute (SwRI), under contract with the Air Pollution Control Technology Verification Center (APCT Center). The APCT Center is operated by RTI International (RTI)† in partnership with the U.S. Environmental Protection Agency’s (EPA) ETV program. The objective of the APCT Center and the ETV program is to verify, with high-quality data, the performance of air pollution control technologies, including those designed to control air emissions from diesel engines. With the assistance of a technical panel of experts assembled for the purpose, RTI has established the APCT Center program area specifically to evaluate the performance of diesel exhaust catalysts, particulate filters, and engine modification control technologies for mobile diesel engines. Based on the activities of this technical panel, the Generic Verification Protocol for Diesel Exhaust Catalysts, Particulate Filters, and Engine Modification Control Technologies for Highway and Nonroad Use Diesel Engines1 was developed. This protocol was chosen as the best guide to verify the immediate performance effects of the PMF GreenTec 1004205.00.0. To determine these effects, emissions results from a heavy-duty highway diesel engine were compared to emissions results obtained operating the same engine with the same fuel, but with the PMF GreenTec DPF technology installed. The specific test/quality assurance (QA) plan addendum for the ETV test of the technology submitted by PUREM was developed and approved in August 2006.2 The goal of the test was to measure the emissions control performance of the PMF GreenTec DPF technology and its emissions reduction relative to an uncontrolled engine
